SHADE-HOLDlNG LAM P-SOCKET.

SPECIFICATION forming part of Letters Patent No. 778,795, dated December27, 1904.

Application filed November 26, 1902. Serial No. 132,912.

To all 1071,0772 it may concern:

Be it known that I, HENRY T. PAIsTn, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Shade-Holding Lamp-Sockets, of which the following is aspecification.

My invention relates to certain improve" ments in incandescent-lampsockets, consisting more particularly in an improved structure of thischaracter especially designed to provide a holder for a lamp-shade, theobject of the invention being to provide a simple and inexpensiveconstruction of permanently-connected lamp-socket shell andshade-holder, such that there is no possibility of these two elementsbecoming detached from one another either when subjected to prolongedvibration or rough or unusual treatment. These objects 1 secure ashereinafter set forth, reference being had to the accompanying drawings,in which- Figure l is a side elevation, partly in section, of myimproved shade-holding lampsocket, showing the detail construction ofthat portion of the same hereinafter described. Fig. 2 is an invertedplan view of the socket shown in Fig. 1, and Fig. 3 is a sectionalelevation showing the detail construction of a special form of mydevice.

In the above drawings, A and A represent the two portions of a shell ofan incandescentlamp socket of well-known form, the former of thesepreferably consisting of two cylindrical sections a" and uf" ofdifferent diameters. There is provided within the socket apparatus B forthe connection of electrical conductors, and this has in the presentinstance a key 7), by which a suitable switch of any desired design,forming a part of the apparatus B, may be operated to turn on or cut offthe current for an incandescent lamp held in the socket. One of theterminals of the socket is shown at 7/, this having attached to it inthe present instance an L-shaped piece of brass 6 extending into thebottom of, but insulated from, a threaded cylindrical piece O for thereception of a lamp. This piece is designed to contact with one of thelamp-terminals, of

which the second terminal engages the brass piece C when a lamp isplaced in the socket. An insulating-lining D extends within the interiorof the outer portion or member of the socket'shell, so as to prevent thepossibility of contact between any of the live mechanism within thesocket and the said shell.

In carrying out my invention I prefer to use an incandescent-lamp shellof the standard and well-known type, which is at present of the formshown in the drawings, being provided with an annular shoulder a nearthe lower end of its portion A.

The shade-holder E consists in the form illustrated of an inner and anouter ring e and 0, connected by radially-extended arms 0 and the innerof these rings is flanged so that its flanged portion will fit snuglyaround the outside of the cylindrical portion of the shell A between theannular shoulder a and the open end of the socket. After theshade-holder has been put in place the extreme edge a of the said shellA is turned or bent from the position shown in dotted lines at a in Fig.l to the position shown in full lines by spinning or other suitablemethod, andthereby retains the shade-holder permanently and rigidly inposition upon the lamp-socket. If desired, this permanent connection maybe secured by means of riveting, as suggested in Fig. 3, the rivetspassing through the flanged portion 12 of the shade-holder and theportion of the shell A between the shoulder a and the end of said shellportion.

1 claim as my invention 1. The combination of an incandescent-lampsocket shell having an annular shoulded adjacentto its open end and asecond shoulder at said end with a shade-holder attached to thesocket-shell and provided with a portion permanently confined betweensaid two shoulders, substantially as described.

2. The combination of an incandescent-lampsocket shell having aprojection adjacent to its open end, a shade-holder having a portionfitting over said open end and abutting said projecting portion, saidend portion of the socket being turned over and thereby permanentl-y andrigidly holding said shade-holder in position, substantially asdescribed.

3. The combination of an incandescent-lamp socket having an annularshoulder adjacent to its open end and having a substantially cylindricalportion between said end and the shoulder, a shade-holder having aflanged portion fitting said cylindrical portion of the socket, a partof said cylindrical portion being bent to engage said shade-holderthereby rigidly and permanently holding the same to the socket,substantially as described.

4:. As a new article of manufacture, a combined incandescent lamp socketshell and shade-holder formed of separate socket-shell and shade-holderportions, said shell portion having aprojection, said holder portionsurrounding said shell and abutting against said
